Sorry to bother you, do you know how to get the other endings?
Main 4 endings
1) If you rescue carlson under specific rescue count, it'll be good ending. Or, it'll be bad ending. (rescue count increased when you move in the dungeon, or click and search at the room)
2) While you're in a bad ending, if you collect all Orc's clue, it'll be true bad ending. If you're in a good ending, if you collect all Captain's clue, it'll be true good ending.
